TO ALL WHOM l'l MAY CONCERN: 4 ,i

Be it known that I, CHARLES T. PooLEIt, of Deansviile, in the county of Oneida, and State of New York, have invented a new and improved Perpetual Calendar; and I do hereby declare that the following is a full,- clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference boing had to the accompanying drawings, formingnpart of this specification, in which- Figure 1 represents a front elevation of my improved perpetual calendar.`

` Figure 2 is` a vertiealtransverse section of the same, taken on the plane ofthe line zum, fig. 1.

Figure is a horizontal section ofthe same, taken on the plane of the line yy, g. 2& i

Similar letters of reference indicate corresponding parts.

This invention relates to 'a new calendar, which is so Aarranged that it can lle used continually to record .the days of the week or month, and that the' days of the week can b e set over the gures of each lnontlrin such a manner that the device is applicable for each year.

The invention consists chiey in the combinationof an endless or other band wound around two vertical rollers, so as to cover partly another band woundI around horizontal rollers.

On the former band are marked Athe names of the days ofv the week, and ou the latter band the names of the successive months, and the rows of figures pertaining thereto..

At the'eommencement of each year the week-band is moved so as tof bringV the required day of the week over the figure I ofthe month-row, and thusthe week-baud isset for'thewhole year, 'except in some years',

when it will have to be adjusted again to the' 1st day of March, whilethe ino'in'thhandhas to he set every months.

A third bami, having theiigurcs 1 to 31 marked uporvits'ffaee,may"l also be arranged i'n conjunction with the above, to display one of its figures `through a hole in the frame ofthe calendar, said figure indicating the day ot' the mont-li, and saidband'havingto be s et` every day.

A, in the drawing, represents the frame of my improved perpetual calendar.

This frame is made of wood, metal, or other suitablematerial, of suitable size and shape. lIn it are the bearings for two horizontal axles, B B, around which a band, C, iswound, upon thefaee of which the names of the months, andthe rows of figures pcrtaningto the samp-e, aresvuccessively printed or others;

wise marked.

In the front plate a of the frame A is a hole, Z1, through which the rows pertaining to one mouth, and thef,

name of the month, are'visihle.

By turning one of the axles, the band() can be wound around it, andu'nwound from the other, so as to displaythe required month, with its rows eilig-ares, through the-hole af D D are two vertical rollers arranged in the frame A, and carrying a narrow band,lE, upon which the names of the week-days orA their initials are printed or otherwise marked.

This band fits over the front of the b and C, and its marksn are spaced correspon-ding'with tllexowsof figures on C. y

,By turning one of thc axles D the band E can` beadjusted so as to bring the required marks in line with the figures on the ban-d Cas is clearly shown in iig. 1.4 i p i The axles B haveprojecting ends c c on the outside'of the., frame A, so that` they can he turned without opening the frame. A' y i f' l' i v But to prevent the accidental or mischievousv disturbance of the hand E, its axles D do not extend outward, and the band can only be turned'by opening the frame A and reaching the rollers D.

For this purpose the upper portion Gr of the back plate d of the fratrie is hinged to` the lower xed partV of the same, as shown in fig. 2. I

In conjunction with the aforesaid devieffejnay also be used a band, H, `fitted around rollers I, as shown, and Aserving to display one of its vthirty-one gure's through a hole,"c, in the rfront plate of the. frame, as shown I ela-im es new, and desire to secure by Letters Patent#- 1. A perpetual calendar, consisting` of the bands ,C end/E Working respectively :trouml horizont-:tl :tud` vertical rollers, substantially as herein showmaml described. r i A 2. The perpetual calendar, wl1en'providcd-witll the lbends C and E, of which the letter partly covers the former, in combination with the hinged porton- G of the frarriein which the device is held, as set forth. 3. The band H :ind rollers I, iin combination with the device set forth in the foregoing clauses.
